What people said

—7 is the world's favorite number. 18% of all answers, more than twice the runner-up (5). It ranks first in every one of the top ten countries and in every age group. Japan is the most devoted at 27%.
—Odd beats even, 63% to 37%. Two thirds of everyone picked a single digit.
—13 is a Western thing. Spain 4.4%, United Kingdom 4.3%, United States 4.3%. Turkey 0.4%, Algeria 0.4%, Pakistan 0.7%.
—Japan does not avoid 4. Tetraphobia predicts a dip, but Japan picks 4 at the global rate.
—67 is a live meme. Third place overall, driven almost entirely by the Philippines (8.8% there) and by respondents under 18. It nearly disappears between ages 30 and 49.
—Preference for 7 grows with age, from 15% under 18 to 21% at 50 to 64.

Columns

One row per person who answered.

Column	Description
`answer`	The favorite number as a float. Almost always a whole number, but `3.14` and `7.5` are in here too.
`answer_raw`	What the respondent actually typed, with surrounding whitespace trimmed.
`country`	ISO 3166-1 alpha-2 country code of the respondent.
`language`	Language the respondent uses on the network.
`age`	Predicted age bracket: `0-17`, `18-29`, `30-39`, `40-49`, `50-64`, `65+`. May be empty.
`gender`	Predicted gender: `Female`, `Male`, `Other`. May be empty.
`occupation`	Predicted occupation or education status. May be empty.

Age, gender and occupation come from Rapidata's demographic model rather than self-report, and are empty for roughly a fifth of rows. Rows are shuffled.

How answers were cleaned

Respondents typed free text. We kept an answer when it contained exactly one distinct number, so 7, 67!!!, 3.14, 8 i like how simple it is and 7 typed twice all count, while 6-7, 2 and 4 and dates do not. Answers that were only a spelled-out number, such as seven or siete, count too. Numbers above 2^53, which are all mashed keyboards, along with letters, symbols and "I don't have one", were dropped. About 6% of responses were removed this way.

Quick start

python

from datasets import load_dataset
df = load_dataset("Rapidata/favorite-number")["train"].to_pandas()
df.answer.value_counts(normalize=True).head(10)
